Hi When hot water is turned on the Burner light comes on but goes off after a couple of seconds then comes on again does this a few times then stays on and all is OK Just run out of guarantee, Is there anything i can do or do i need an engineer.
It could be the diaphragm, the flow switch, the air pressure switch, overheat stat so on & so on. Infact countless things but sorry there is nothing you can do as it is ilegal to work on any gas appliance unless you are a Gas Safe Registered engineer. So you will need an engineer.
